This email address does not belong to Barclay. So the email is fake.
Generally speaking, each and every bank's email address ends with the bank's domain name (i.e. the portion after @). When you have @accountant.com as the domain name, it is a clear sign that the email address does not associate with the bank.
Also, for security purposes, banks will not usually send emails to their customers unless: 1) the emails are advertisements; 2) the email are related to the account, but without account information; 3) It is a response of an email you have sent.
